What is a humidity sensor on a Mack truck?
Took to Mack Dealer outside New Orleans, LA, and they put a computer on the truck that said it was a “humidity sensor”.

What does a lightning bolt light mean on a truck?
The truck is running fine, no issues. Just have no clue what the light means. If your dealer didn’t know what that light was all about, then you need to go to another dealer. I wouldn’t trust them to work on the truck. Either they are clueless or they blew you off.
When did Mack start using AC and AI engines?

Why is the turbo on my Mack truck not working?

How to check the electronic malfunction light code?
You can check the code. With your cruise control switch OFF, press the set button and the electronic malfunction light will blink the code. So let’s say it’s code 4-1, the light will blink 4 times, pause a second or two, and blink 1 time, then go back to constant. If there is more than one code, press the bottom again, and the next code will blink.
Why are the engine and power loss lights on?
All the fluids are fine and there was no shutdown and/or power loss. Truck is a 97 CH. BMT Certified Know-It-All! The only time both lights come on is for low coolant, (except for 2008 and up DPF equipped Macks). Could be a coolant sensor wire shorted in the harness on the engine. BMT Certified Know-It-All!
